Agent and method for the temporary deformation of keratin-containing fibers

Abstract

Cosmetic compositions for the temporarily shaping of keratinic fibers and methods for using such cosmetic compositions are provided. In one example, a cosmetic composition includes at least one non-crosslinked, hydrophobically modified (meth)acrylic acid copolymer, and at least one copolymer that includes at least in part monomer units. The monomer units include styrene, and acrylic acid and/or methacrylic acid.

The invention claimed is: 
     
       1. A cosmetic composition for the temporary shaping of keratinic fibers, comprising:
 a) at least one non-crosslinked, hydrophobically modified (meth)acrylic acid copolymer, wherein the at least one non-crosslinked, hydrophobically modified (meth)acrylic acid copolymer a) has the INCI name Acrylates/C 10-30  Alkyl Methacrylate Copolymer, and 
 b) at least one copolymer comprising at least in part monomer units including: 
 
       styrene, and 
       acrylic acid and/or methacrylic acid, wherein the at least one copolymer b) has the INCI name Styrene/Acrylates Copolymer; and
 wherein a proportion by weight of the copolymer a) in the total weight of the composition is about 0.5% by weight, and wherein the proportion by weight of the copolymer b) in the total weight of the composition is about 0.5% by weight. 
 
     
     
       2. The cosmetic composition according to  claim 1 , wherein the cosmetic composition is selected from the group of a hair gel, a hair spray, a hair mousse, or a hair wax. 
     
     
       3. The cosmetic composition according to  claim 2 , wherein the hair gel, the hair spray, the hair mousse, and the hair wax are formulated for the temporary deformation of hair. 
     
     
       4. The cosmetic composition according to  claim 1 , further comprising:
 c) polyvinylpyrrolidone and/or vinylpyrrolidone/vinyl acetate copolymer. 
 
     
     
       5. The cosmetic composition according to  claim 4 , wherein the proportion by weight of the polyvinylpyrrolidone and/or vinylpyrrolidone/vinyl acetate copolymer c) in the total weight of the cosmetic composition is from about 0.1 to about 10% by weight. 
     
     
       6. The cosmetic composition according to  claim 4 , wherein the proportion by weight of the polyvinylpyrrolidone and/or vinylpyrrolidone/vinyl acetate copolymer c) in the total weight of the cosmetic composition is from about 2.0 to about 8.5% by weight. 
     
     
       7. The cosmetic composition according to  claim 4 , wherein the proportion by weight of the polyvinylpyrrolidone and/or vinylpyrrolidone/vinyl acetate copolymer c) in the total weight of the cosmetic composition is from about 3.0 to 7.0% by weight. 
     
     
       8. The cosmetic composition according to  claim 1 , wherein the composition comprises, based on its total weight, at least about 20% by weight of water. 
     
     
       9. The cosmetic composition according to  claim 1 , further comprising:
 c) polyvinylpyrrolidone. 
 
     
     
       10. The cosmetic composition according to  claim 1 , wherein the composition comprises, based on its total weight, at least about 40% by weight of water. 
     
     
       11. The cosmetic composition according to  claim 1 , wherein the composition comprises, based on its total weight, at least about 70% by weight of water. 
     
     
       12. A method comprising using a cosmetic composition according to  claim 1  for the temporary deformation of keratin-containing fibers. 
     
     
       13. A method for the temporary deformation of keratin-containing fibers, the method comprising acting upon the keratinic fibers by a cosmetic composition according to  claim 1  while the keratinic fibers are temporarily fixed in a shape.
